Application filed January 30, 1929. Serial No. 336,124.

This invention relates to proctotherapy apparatus of the class disclosed in my Patent No. Re. 16,251 dated January 12, 1926, and

more particularly to an improved valve constructlon for use 1n such apparatus.

present invention has in view are To provide an improved three-way valve arranged so that the same may be quickly dismantled or disassembled for sterilizing after use, and

reassembled for treating another patient, reducing the time between treatments to a minimum; to provide an improved valve construction which will control the admission of one or more fluids through the inlet passage to the injector tube and when turned to the exhaust position will permit the fluids dis charged through the injector tube to drain back through the outlet or discharge passagein the valve to a waste receptacle, thereby, never permitting any portion of the valve; through which the clean unused fluid passes to come in contact with that portion of the valve used for discharging the polluted fluid and to provide visual means on the valve to indicate the position of the valve ports. Other objects will appear as the description proceeds.

Description wall or seat and three integrally connected tube connections 11, 12 and 13, for connection with the fluid supply, the outlet or in jector connection, and the drain or waste connection, respectively. The outer end of the injector connection 12 is provided with a Among the principal objects which the.

resilient clamping member 11 for holding the flexible tubing attached to the injector nozzle in fixed position thereon. The drain connection 13 is bent downwardly to facilitate the discharge of the polluted waste fluid, while the supply connection 11 is exteriorly threaded at 15 for attachment with an arm or branch 16 of the three-way fitting 17 each branch of which is controlled by separate valves 18, 19 and 20, and in turn are connected with containers 21, 22 and 23, containing water and one or more medicated fluids. A. wing nut 24 swivelly mounted at the outer end of the arm 16 of the fitting 17 is adapted to thread on to the threaded'portion 15 of i the connection 11 tohold the said parts in rigid coupled position. A supporting arm 24* is connected with the fitting 17 and serves to support the valve assembly and fitting to the table 25 upon which the patient is placed.

The valve body 26 is conical in shape and isadapted to fit. snugly within theconical seat in the casing 10, and is provided with a pair of spaced parallel passages 27 and 28, respectively for the clean fluid and for the usedor waste fluid, which passagesare adapted to register with the fluid supply'connection and injector connection, and the injector connection and the waste or drain connection. An operating handle 29 extends upwardly from the valve body 26 for moving the same as desired. A cylindrical shank 30 extends downwardly from the lower surface of the body 26 and terminates in a reduced threaded portion 31. The rigid washer 32 is adapted to fit over the shank 30 and to seat on the lower face of the valve casing 10, and is securely held thereon by a resilient washer 33 having a plurality of springfingersof said washer 33 engageable with the said washer 32, and.

forced thereagainst under tension by the looking nut 34 on the threaded portion 31 of the shank 30. A quadrant 35 is secured between the connections 12 and 13 and is provided with spaced lugs for limiting the throw of the valve, and cooperates with an indicating finger 36 carried by the valve body 26, and serves to indicate the position of the passages in the said valve.

It is therefore apparent that after a pa tient has been treated, it becomes necessary to thoroughly sterilize all parts of the valve and its associated assembly or fittings before the same may again be used for another patient. By unscrewing the wing nut 84 and the locking nut 84, the valve may be quickly disassembled and placed in a sterilizing device, and all parts thereof positively sterilized,thereby preventing any infection being transmitted from one patient to another.

it will further be seen that the desired flow and mixture 01 the fluids may be easily regulate-d to efficiently treat the patient.

Many minor changes in detail of construction may be resorted to without departure from the spirit of the invention.

Claims:

1. A valve mechanism as characterized comprising a swinging bracket member having a fitting embodying multiple receiving passages converging into a single delivery passage, and a valve assembly embodying a cup-like casing having a plurality of tubular extensions, one of which being a receiving passage, is adapted for operative connection with said delivery passage on said swinging bracket, said assembly further embodying a rotatable valve body having a plurality of passages therethrough adapted to register the one with said receiving passage and simultaneously with one of said tubular extensions, and the other passage being adapted to register with said receiving passage and the other tubular extension when moved thereto; and means readily operable for operatively connecting and releasing said casing and said bracket, and separate means readily operable to operatively connect said casing and said valve body.

2. A valve mechanism as characterized comprising a swinging bracket member having a fitting embodying multiple receiving passages converging into a single delivery passage, and a valve assembly embodying a cup-like casing having a plurality of tubular extensions, one of which being a receiving passage, is adapted for operative connection with said delivery passageron said swinging bracket, said assembly further embodying a rotatable valve body having a plurality of passages therethrough adapted to register the one with said receiving passage and simultaneously with one of said tubular extensions,

and the other passage being adapted to register with said receiving passage and the other tubular extension when moved thereto; and means readily operable for operatively connecting and releasing said casing and said bracket, said means consisting of a wing nut,

and means readily operable for operatively connecting said casing and said valve body, said second mentioned means embodying a spring seated washer bearing on said casing to close the same and to secure the valve body firmly in said casin OSCAR eoro SCHELLBERG.
